What the WATER ADAPTER does
Connections, adapters and fittings join lines and components while holding pressure at the joint. Each one is a potential leak point, and on a percussion circuit each one is being vibrated continuously.
Signs it needs replacing
- Weeping or seepage at the joint
- Damaged sealing faces, cones or threads
- Fittings that loosen repeatedly
- Cracking at the fitting body
Before you fit it
Torque fittings to specification rather than to feel — overtightening damages the sealing face and creates the leak it was meant to stop. Renew soft seals whenever a joint is broken.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
